The actual amounts we pay
 to our regional operators under CPAs could differ materially from
 these estimates. For example, a 10% increase or decrease in
 scheduled block hours for all of United’s regional operators
 (whether as a result of changes in average daily utilization or
 otherwise) in 2017 would result in a corresponding change in annual
 cash obligations under the CPAs of approximately
 $147 million.
